Flash Temperature Parameter (FTP) is the temperature at which a lubricant ceases to function effectively, leading to metal-to-metal contact, increased friction, wear, and possible equipment failure. This study explores the impact of TiO2 nanoparticles in trimethylolpropane trioleate (TMPTO)-based bio-lubricants on the Flash Temperature Parameter. A four-ball tester assesses the Anti-Wear Scar Diameter (AWSD) of TMPTO-TiO2 nano-lubricants at varying concentrations under controlled speed, load, and temperature conditions. The FTP is determined from the average AWSD measured on the bottom three balls. Results from Taguchi experiments and corresponding signal-to-noise ratios were used to rank the parameters. The combination of TMPTO base oil and TiO2 nanoparticles synergized to enhance FTP. FTP assesses a lubricant’s performance under high load and temperature conditions, such as in rolling mills and cutting processes. This research may benefit specialty lubricant manufacturers. Further studies on the wear mechanisms of TMPTO-based nanolubricants and their potential for high-speed metal cutting applications are recommended.
